Ins tallation  
Figure 1: Front Panel Connections of the SC-600D amplifier.  
Following are brief descriptions of the controls described in Figure 1. More detail on these  
controls can be found in the next section.  
(1) Power Switch  
This button forces your SC-600D amplifier into standby mode. The power LED turns amber,  
the numeric LED shuts off, and the amplifier puts out no power. The unit will remain in this  
mode until the POWER button is pressed again. To fully deactivate (i.e. power down) the unit,  
use the main power switch on the back panel.  
(2) Power LED  
This LED illuminates when the power is on. Blue indicates normal operation. The LED turns  
amber when the unit is in standby mode or the remote has been used to deactivate the unit,  
and dims when the unit is in night mode.  
(3) Mic Input  
Connect the supplied microphone for the Auto-EQ feature to this mini-jack input.  
(4) Remote Eye  
This is the eye that receives infrared commands from the supplied remote.  
(5) Crossover  
Use these Up and Down buttons to select the frequency below which all signals will be routed  
to the subwoofer (for example, 80 Hz), rather that to the main speakers. The frequency is  
indicated on the LED display, then the display reverts to showing the subwoofer’s volume  
level. The slope is fixed at 24 dB/octave. To deactivate the crossover, press BOTH the Up  
and Down crossover buttons at the same time – two dashes on the display indicate the  
crossover is deactivated and the woofer plays all frequencies presented to it. Please see  
page 8 for a more detailed discussion on crossovers.

(6) LED Numeric Indicator  
This LED supplies information on volume, crossover, woofer type, and other information. The  
“light” button on the remote deactivates this display. Upon startup, the display shows the  
model of subwoofer the SC-600D amp is controlling, then reverts to the volume indicator.  
(7) Volume Control  
These buttons allow you to balance the output from the subwoofer to the main speakers in  
your system. The volume should be set to achieve similar volume level of both the main  
speakers and subwoofer. The default volume is 30.  
Note: Volume can also be controllable by using the supplied remote.  
WARNING: Some manufacturers preset their receivers with the Sub-Out (a.k.a. LFE)  
channel signal at a minimum level. It is very important to verify that your receiver Sub-Out  
channel is set to the same output level as your front right and left channels. Refer to your  
receiver manual for the individual channel level adjustment procedure. If your receiver Sub-  
Out channel is set too low, the subwoofer may appear to have a weak output, it may sound  
noisy or distorted, and the Auto On/Off feature may not operate properly.  
(8) Optional Rack Mount Ears (Included)  
These ears can be attached to the SC-600D amp to allow standard 19” rack mounting.  
REAR PANEL CONNECTIONS  
Following are brief descriptions described in Figure 2. More detail on these controls can be  
found in the next section.

(9) Thru Jacks  
These RCA connectors are for passing along the same signal that goes into your subwoofer  
to a second “daisy-chained” system. The signal from these RCA connectors is the same as  
the input signal.  
(10) Line Input / LFE Input  
Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks  
of your receiver/processor. If using the LFE output from your receiver or processor, plug  
the single cable into the jack labeled LFE input or, for more signal, use a “Y” connector  
(optional) and feed the signal into both “R” and “L” inputs. Examples of these types of  
connections can be found in Figures 2A and 2B.

(11) IR Input  
An IR repeater can be connected to this mini-jack.  
(12) 12V Trigger  
When this 2-conductor mini-jack is connected, the amplifier remains in power-off mode until  
the trigger is applied. The correct trigger is +12V on the tip of the connector relative to the  
grounded sleeve.  
(13) RS-232 In  
Use this port to communicate with an RS-232 controlled touch panel system. See Appendix  
A for an explanation of the use of the serial port, available commands, and their formats.  
(14) Signal Sensing Auto On/Off Switch  
With this switch in the “standby” position, your subwoofer can be safely left with the main  
power switched on continuously. The subwoofer amplifier will turn itself on automatically when  
an audio signal is present. If no signal is present for approximately 10 minutes, the unit will  
switch to standby mode. While in standby mode, your subwoofer amplifier will draw very  
minimal power. This function can be disabled by leaving the switch in the “always on” position.  
(15) Speaker Level Input Terminals  
If you do not connect the SC-602 amplifier to your receiver using the line input/LFE input  
connection (Item 10), connect these input terminals to the speaker output terminals of your  
amplifier or receiver. If you use this method of connection, make sure to select the “large”  
speaker option in the receiver’s set-up menu. Also, select the option for no subwoofer. This  
will make sure all bass and LFE information is fed the speaker outputs and be received by  
your SC-600D amplifier.  
Note: Using both speaker terminals and the line level inputs is not recommended, as this may  
damage the SC-600D amplifier or your receiver.  
(16) Speaker Level Output Terminals  
These connections send a crossed-over speaker-level signal to the front speakers. When  
connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes  
the lower bass frequencies from your satellites, enabling them to do a better job reproducing  
high frequencies.  
You may also connect your satellites directly to your receiver or amplifier along with the  
subwoofer if you wish to bypass this crossover.  
An example of a speaker-level connection is shown in Figure 3.

Figure 3: Speaker-Level Connection.  
(17) Subwoofer Connection 5-Way Binding Post Terminals  
Connect the output terminals to the subwoofer being controlled by the SC-600D amplifier.  
Only connect ONE subwoofer to the red/black pair of subwoofer output terminals - DO NOT  
connect multiple subwoofers to the terminals in any configuration.  
Caution!!!  
To avoid damage to your SC-600D amp and subwoofer, be sure to maintain correct polarity  
when making all speaker connections; red (positive) to red, and black (negative) to black. Be  
sure that all connections are tight, and that there are no loose strands or frayed wires.  
(18) Power Cord Adapter  
Connect the detachable power plug to this male interface connection. The detachable cord  
allows for easy replacement should the original become damaged.  
(19) Fuse  
If the unit is not functioning, check the fuse. If the fuse is blown, replace with an identically  
rated fuse. If the fuse blows again, refer the unit for service.  
(20) Main Power Switch  
Press the POWER switch to the ON position to activate the amplifier. If the unit is to be left  
unused for an extended period of time, move this switch to the OFF position to prolong the  
life of the amplifier.

Rear Panel Connections — Detailed Explanation  
The SC-600D amplifier is equipped with both speaker-level and line-level inputs. Use the  
RCA/Phono type “INPUT” jacks when connecting from a pre-amp, signal processor, or line-level  
crossover. The “SPEAKER LEVEL INPUT” jacks connect directly to the speaker outputs of an  
integrated amplifier or receiver. Your amplifier section will notice no additional loading effects  
when you use these inputs because of their high impedance.  
Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT”  
connections simultaneously.  
ABOUT LOW-PASS CROSSOVERS  
All of the SC-600D amplifier inputs sum the left and right channels together and the resulting  
signal is passed through an adjustable low-pass crossover before being amplified. The crossover  
control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to  
160 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control  
to. The slope is 24 dB/octave.  
You should set the crossover frequency to obtain a smooth and seamless transition from the  
subwoofer to the main speakers in your system. If your main speakers are smaller with limited  
low frequency output, you may wish to choose a higher frequency (such as 100 -120 Hz) than  
you would with larger speakers which have greater low frequency output. The SC-600D amp’s  
crossover has a default of 80 Hz.  
Most receivers and processors provide a menu option in which you can characterize main  
speakers as “large” or “small” speakers. This affects the bass signals passed to the main  
speakers. We recommend in most cases setting the main speakers to “small,” despite their  
size and frequency response characteristics, allowing all multi-channel bass and LFE signals to  
be passed to the SC-600D. This is because the powerful 400 watt SC-600D amp combined  
with the SC-600 subwoofer are more likely suited to low bass reproduction than your amp and  
main speaker. With the burden of low frequency reproduction relieved, your speakers will exhibit  
better performance, and your overall system performance will improve.  
Disabling the Low-Pass Crossover (Subwoofer Direct)  
If your receiver/processor provides a crossed-over signal to the subwoofer, you may want to  
bypass the SC-600D amp’s low-pass crossover. To do this, depress BOTH the Crossover UP  
and Crossover DOWN buttons simultaneously. The numeric LED will show  
the low-pass crossover has been defeated. To reactivate the low-pass crossover, simply push  
the crossover UP or crossover DOWN buttons.

A WORD ABOUT YOUR HOME THEATER RECEIVER’S  
CROSSOVER AND THE SC-600D AMPLIFIER’S CROSSOVER  
Your Velodyne SC-600D amplifier is designed to operate using the full range audio signal for  
input when using the built-in crossover. Many home theater processors/receivers have a  
“subwoofer out” jack that performs this same function and are designed to be used with a  
powered subwoofer.  
w w w . v e l o d y n e . c o m  
SC-600D Amplifier User’s Manual

In these installations, you may want to bypass the crossover in either the processor or the  
Velodyne SC-600D amplifier as described above. However, in some cases you may want to use  
BOTH crossovers. If you choose to do this you should stagger the frequencies, (i.e., 120 Hz  
subwoofer, 80 Hz processor) for best results.  
Note: If not using an external crossover, you should use the subwoofer’s built-in crossover for  
optimal performance. When using a single RCA sub out from the processor, it does not matter  
which line level input (L/R) is used.  
A WORD ABOUT INTERCONNECT CABLES  
When installing your Velodyne SC-600D amplifier using the line-level connections, you should  
always use high quality shielded interconnect cables. It is recommended that you keep the  
length of cable as short as possible to avoid any potential external interference problems.  
When connecting the SC-600D amplifier to your subwoofer, use a quality speaker cable that is  
at least 14-gauge. Be very careful to avoid any loose or frayed strands that could result in a  
short, causing a dangerous condition and possible damage to your unit. Cables of extremely  
large size are typically not required. Extremely large gauge wire may not properly fit in the  
binding posts, resulting in a poor connection and possible short circuits.  
A WORD ABOUT SUBWOOFER PLACEMENT  
Subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in  
mind that frequency response and output level can be drastically influenced by room placement,  
depending on the acoustic properties of the listening room. Typically, the optimum location for  
a subwoofer is in a front corner of your listening room. This location will usually offer the  
greatest output levels and optimum low frequency extension. Typically, a minimum distance  
of one to two feet from your TV to the subwoofer will be adequate to avoid any  
magnetic interference.  
Remember that the built-in 5-band EQ will help to get the most performance out of your  
subwoofer no matter where it is placed.  
Caution!  
This amplifier is an electronic device. Do not place the amplifier next to sources of heat such  
as furnace registers, radiators, etc. Likewise, do not place the amplifier near sources of  
excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be  
routed in such a way that it will not be walked on, pinched or compressed in any way that could  
result in damaging the insulation or wire.

Selecting the Subwoofer to be Controlled  
Your SC-600D amplifier can control the Velodyne SC-600 Series subwoofers as well as generic  
passive subwoofers. Special internal software settings are designed to maximize performance  
and reliability depending on the model of subwoofer being controlled, so it is important to match  
the SC-600D amplifier with the subwoofer it is controlling. The SC-600D amplifier comes with  
a default setting for the SC-600 IW subwoofer. When the unit is first powered up, the model  
being controlled is displayed for two seconds on the numeric LED before the display reverts to  
the volume setting. The subwoofer to be controlled is shown as follows:  
Model  
LED Display  
SC-600 IW (In-Wall)  
I W  
SC-600 IF (In-Floor)  
SC-600 IC (In-Ceiling)  
Generic Subwoofer  
I F  
I C  
GS  
Note: Both the IF and the IC settings control the SC-600 In-Floor/In-Ceiling (IF/IC) subwoofer  
and have identical internal settings.  
To change the subwoofer to be controlled, first power down the amplifier using the main power  
switch on the back panel (DO NOT use the power button on the front panel). Then, turn the  
switch on while depressing any of the buttons on the front panel (crossover up or down, or  
volume up or down). The unit will show the model it is currently controlling. To change the  
model, simply push the crossover up or crossover down buttons and the model changes on the  
LED display. Once the desired model is seen on the LED display, simply release the button. You  
don’t need to do anything else - the model to be controlled is automatically stored in the  
SC-600D amp’s memory. To exit model selection mode, use the main power switch on the back  
panel to power down and power up the unit. You should see the model you selected for two  
seconds on the LED display before the display reverts to the volume.  
Note: The SC-600D amplifier can control only one subwoofer at a time, either the  
SC-600 IW or SC-600 IF/IC.

Usage  
This section addresses EQ setup and day-to-day usage of your SC-600D amplifier.  
Remote Control  
The features of the SC-600D remote control are listed below.  
• POWER — This button forces your SC-600D amplifier unit into  
standby mode. The power LED turns amber, the numeric LED  
shuts off, and the amplifier puts out no power. The unit will  
remain in this mode until the POWER button is pressed again.  
To fully deactivate (i.e. power down) the unit, use the main  
power switch on the back panel.  
Note: The master power switch on rear panel must be on in  
order for the front power button to function.  
• MUTE — This button mutes the subwoofer’s output. The LED  
on the amplifier will show 00 if the unit is muted. To unmute  
the subwoofer, press the MUTE button again and the original  
Figure 5: SC-600D Remote.  
volume setting shows on the LED.  
• EQ — This button automatically EQs the subwoofer using a 5-band internal graphic equalizer.  
To use this feature, first plug the supplied microphone into the Mic-In jack on the front panel  
of the amplifier and place the mic in your preferred listening position. Then press EQ on the  
remote for about 2-3 seconds. The subwoofer emits 12 “sweep tones” that cover the  
frequencies between 20 and 150 Hz. The LED displays “AU” during the Auto-EQ process.  
After the sweeps are complete, the unit saves its EQ settings and returns to normal  
operation. To prevent accidental invocation of the EQ feature, you must hold down the EQ  
button for 2-3 seconds before the EQ sweeps begin.  
Note: Each time the EQ feature is utilized, the EQ settings for the SC-600D amplifier are reset.  
If the microphone is not plugged in, the SC-600D amplifier will emit one or two sweep tones  
then cease the EQ operation. In this case, the previous EQ settings will be preserved.  
• PHASE — These buttons allow you to optimize the subwoofer performance for the location  
and your listening position. Play some bass-heavy music. While listening, push one of the four  
phase buttons, listen for a few moments, and then press the next phase button. In most  
installations, one of the four button positions will offer an audibly better blend of subwoofer  
and speakers. Selecting the correct phase position is just that easy. The LED will show the  
phase selected by showing “PH” followed by the phase number: 0, 90, 180 or 270.  
• LIGHT If you wish, you can deactivate the numeric LED on your SC-600D amplifier.  
To do this, press the LIGHT button on your remote. To reactivate the LED, press the LIGHT  
button again.  
• NIGHT — Night mode limits the maximum dynamic output of the subwoofer for late night  
listening or to be more considerate of close neighbors. Press the night button to turn the  
night mode feature on or off. Activation of night mode causes “n” to appear briefly on the  
display. When night mode is deactivated, the display shows “n off” and then returns to  
normal function.

• VOLUME CONTROL — This control allows you to balance the output from the subwoofer to  
the main speakers in your system. This control should be set to achieve similar volume level  
of both the main speakers and subwoofer. When pressing volume up or down, the volume  
level change is shown on the numeric LED on the front panel.  
WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a  
minimum level. It is very important to verify that your receiver Sub-Out channel is set to the  
same output level as your front right and left channels. Refer to your receiver manual for the  
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,  
the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto  
On/Off feature may not operate properly.  
Note: The volume can also be adjusted via the volume buttons on the front panel of the  
amplifier. These buttons have the same effect as pressing the up and down volume buttons on  
your remote.  
• PRESETS — There are four presets, consisting of Movies, R&B – Rock, Jazz – Classical, and  
Games. As a preset is chosen, the preset is shown on the numeric LED as P1 for preset 1,  
P2 for preset 2, etc. The presets provide the following characteristics for bass reproduction:  
Movies:  
Maximum output and impact for explosions and other action adventure  
movie content.  
R&B – Rock:  
Provides the driving bass found in today’s rock music.  
Jazz – Classical: The tightest, cleanest, lowest distortion bass. The flattest frequency  
response of the four presets.  
Games:  
Maximum loudness available for the impact of video games.  
Each preset has its own characteristics with respect to subsonic filter, volume differential and  
a single contour equalizer in order to optimize the listening mode for the preset.

Preset 3: Jazz – Classical  
Preset 2: R&B – Rock  
Preset 1: Movies  
When you press the presets in the above order, the numeric LED will display “P3” indicating that  
you have restored defaults. The unit’s volume is reset to level 30 out of 80.  
Care of your Amplifier and Subwoofer  
Do not use any harsh detergents or chemicals to clean the SC-600D chassis or the subwoofer  
cabinet. Abrasives, detergents, or cleaning solutions will damage the finish on the SC-600D  
chassis or the subwoofer cabinet. We recommend using a damp cloth to clean the front, back  
and sides.  
During normal conditions, the amplifier may be left on continuously without any problems. If you  
plan to leave the unit unused for an extended period of time, we recommend that you turn off  
the unit by the master power switch on the rear panel.

T roubleshooting and Service  
Before seeking service for your amplifier or subwoofer, please re-check all systems. Following  
is a simple troubleshooting guide to assist you.  
1. Verify that the unit is plugged in and power outlet used is active.  
2. Is the power switch on?  
3. Is the unit receiving an input signal from your source?  
4. Have all controls on the amplifier (volume, crossover, phase, etc.) been properly set?  
5. If the unit has been running at high levels, one of the protection circuits may be  
engaged.  
Has the amplifier overheated?  
6. Has the power button been depressed on the remote?  
7. Is the remote non-responsive? We recommend replacing the batteries in the remote.  
If the protection circuitry is active, the unit may cycle on and off until operating parameters  
return to normal. Under more serious conditions, the unit may shut off completely. Normal  
operation should return upon cooling, but you may be required to turn the power off and then  
on again to reset the unit.  
The following conditions require service by a qualified technician:  
1. The power cord has become damaged  
2. The unit does not appear to operate normally or exhibits a marked change in  
performance  
3. The unit has been exposed to water  
4. Some part of the chassis or circuitry is physically damaged
